Dirok field starts flow in India

Hindustan Oil Exploration Company (HOEC) has started production of natural gas and condensate from Dirok field near Digboi in Assam.


State-owned Indian Oil Corporation Ltd (IOC), which holds a 29.03% interest in Block AAP-ON-94/1, reported initial production from three wells at 10 MMscfd of gas and 120-140 b/d of condensate.


Produced fluids flow through a 4-inch, 20-kilometre pipeline from a gathering station at the Dirok-4 well to the Kusijan gas processing plant operated by state-owned Oil India Ltd (OIL) four kilometres from Digboi.

OIL, which holds a 44.08% interest in the block, is buying first-phase Dirok gas. IOC is buying the condensate. Private HOEC is operator with the remaining interest.


After a second development phase, Dirok output will rise to 35 MMscfd of gas and 800 b/d of condensate.


That work will include construction of a modular gas processing plant at Borpowai, ten kilometres south of Digboi, and a 12-inch pipeline from the Dirok-4 gas-gathering station to the new facility.
